PERTH, AUSTRALIA--October 10, 2013--Researched by Industrial Info Resources Australia (Perth, Australia)--The Alpha coal project in Queensland is likely to face further delays due to court proceedings initiated by environmental groups that want the mining approval, granted in August of last year, revoked. The project, designed and developed by a joint venture between India's GVK Power and Infrastructure Limited and Hancock Coal Limited, is considered to be one of the largest coal-mining projects in Australia.
